i have installed and activated the Enterprice Package, but i can't use the Plus Package, because my AAM version is too old, but i can't update my plug-ins AAM. Uninstallation is not possible, how can I update the Plug-In or use the Plus Package?
Virtel AAM is a regular WordPress plugin that you can update from the official WordPress repository. If you cannot update AAM, then it is almost certain that you cannot update any other plugins on your site. This is something that you would have to clarify with your hosting provider.
Keep me posted.
